Hello Woolly Bugger: Well... I'm 67 & I know what you mean about the world becoming too much to bear. I feel it too. I do think that, to some extent, it is an age thing. As we get older we gradually lose a lot of vim-&-vigor. Stuff that just used to roll off, starts to stick. We begin to realize how vulnerable we are & that it's just going to become more-so as we get older still.
Personally, I have also felt a strong urge to have a spiritual home. This feeling is, I suppose, aggravated by the fact that I am almost completely solitary. Unfortunately for me, deep down, I am a confirmed atheist. So realistically there is no spiritual home that would be appropriate for me. But I understand your desire & wish you well in your search.
